Paraguayan ufologist Ronald Maidana said that the recent resurgence of global interest in UFOs, now called UAPs (Unidentified Aerial Phenomena), is not new but rather the continuation of a long process of declassifying documents about strange aerial phenomena. In an interview, he explained that since the 1950s, American researchers have been collecting military reports related to sightings, citing names such as Loren Gross, Rob Mercer, and John Greenewald Jr., creator of the website “The Black Vault,” which stores thousands of declassified official documents.
Maidana argued that many of the files recently released by Donald Trump's government had already been circulating among research communities for years. Although he considers the documents authentic, he urged caution when analyzing the political context in which they were released.
The specialist recalled that more than 15 years ago, he found records about alleged Paraguayan cases in archives linked to Project Blue Book and other U.S. investigation programs. Among them, he mentioned a 1948 report about an oval, greenish object observed in Villarrica.
According to Maidana, after years of research, approximately 86% of analyzed cases end up having a rational explanation, usually related to astronomical or atmospheric phenomena or perception errors. However, he stated that there is a percentage of incidents that “do not withstand analysis” and remain without a conclusive explanation.
In Paraguay, there are historical reports of sightings, especially in rural areas where less light pollution makes sky observation easier. Among the most notable cases, Maidana cited an episode from 1991, when a supposed flying object allegedly followed a Líneas Aéreas Paraguayas plane and another aircraft from Concepción for several minutes, a fact that was supposedly recorded by radar.
The researcher also referenced other historical accounts compiled in his book “OVNIs en Paraguay, radiografía de un fenómeno desconocido,” where he documents alleged sightings from the colonial era to the present day.
Regarding theories about extraterrestrials and Area 51, Maidana considered that there are numerous rumors and speculations, but so far there is no compelling scientific evidence to confirm the existence of technology or beings of extraterrestrial origin. “To date, there is no conclusive evidence that allows us to say that something observed is definitively of extraterrestrial origin,” he stated.
Finally, Maidana insisted that each case must be analyzed with scientific rigor and rationality, avoiding hasty conclusions.
